The frame-dragging phenomenon in gravitational fields is revisited to explore the geometric effects induced by spacetime curvature. We quantize a massless scalar field in the spacetime of a rotating sphere, incorporating the frame-dragging frequency into the field modes. The excitation rate for an atom undergoing uniform circular motion and interacting with the scalar field is calculated. Our results reveal that the time-dependent excitation rates of atoms following different trajectories exhibit a common envelope, from which the frame-dragging frequency can be effectively extracted. This discovery leads us to propose a novel detection scheme for measuring the frame-dragging frequency caused by rotating celestial bodies, eliminating the need for traditional starlight calibration methods.
